SPECIFICATION forming part of Letters Patent No. 628,300, dated July 4,1899. q

Application filed January 6, 1 898.

To all whom it may concern:

Be it knownthat I, WYNFoRD BRIERLEY, a subject of the Queen of GreatBritain and Ireland, residing at 'Nelson,'in the county of Lancaster,England, have inventednew and useful Improvements in and Connected withApparatus for Signaling on Railways,of which the following is aspecification.

The principal object of the present-invention is to construct anefficient railway signaling apparatus to give both an audible and aVisible signal on the engine or train as to the position of thesemaphore-signal, whether it is at danger or at -safety, and also toprovide specially-suitable signals on the engine or train and a specialcontact-bar (and-adj uncts therefor) on the permanent way.

- In carrying out one feature of my invention I prefer to avail myselfof the type of. railway signaling appliances illustrated in myapplication for patent, Serial No. 664,099, and that form of it inwhich'a swinging lever is mounted on the engine or other suitable partof the train in such a'position as to come into contact with a suitableprojection upon the permanent way, this projection being movable andoperated by the signalman or otherwise as the line is clear or blocked.This swinging lever is connected to apparatus constructed to operate ahell or other alarm on the train, and the lever is preferablyheld innormal'central position by .two reversed springs, so that the lever willact equally whether the train is moving in one direction -or the other,andthis withoutundue shock or injury. The controlling projection on thepermanent way can be operated by the work-' ing of the semaphore.

' In the accompanying'drawings, Figure 1 is a vertical section ofthe'lever-box on the engine or other suitable part of the train. Fig. 1is a sectional view on the line 1 1, Fig. 1. Fig. 1 is a sectionalviewon the line 2 2, Fig. 1. Figs. 2, 2, 8, 3, ands are views of theimproved electrical signaling appliance on the engine. Figs. 5, 6, and 7are views of my improved contact-bai' upon thepermanent way, and Figs. 5and 6 are views of a modification.

Referring to'Figs. l, 1, and 1 it will be.

observed that I construct the operating-lever a and its adjuncts (uponthe engine or other suitable part-of the train) in duplicate to effectthe operation of corresponding signals upon the engine. In the bOXAJ fiXtwo shafts a, and a the firstcarrying the pendent lever a and the secondcarrying the pendent lever a., The levers a a are held in their normalcentral positions (as in my application Serial ver in either directioncauses springs a to come into contact with the springs 6%, Fig. 1,

the wires a anda or (1 01. as the case may 'or a Fig. 1, to close thecircuits through be. These wires a a and a a are connected up to the twosets of electromagnets in the signaling-box D on the engine. This box D,as shown in Figs. 2, 2 and 4, is provided with an'audible signaling gongor bell d, common to both danger and safety signals. The visibledanger-signal is'a disk d on a swinging lever d Fig. 2, and is moved toa position where it will show through an opening D in the face of thebox D, Figs. 2 and 3, when the lineis blocked or the semaphoresignal isat danger. The visible safety-v signal is a disk (1 Fig. 2, on a lever-dand adaptedto be moved behind an opaque spaced shutter D Fig. 2, in thefront of the casing or box D, so as to show the letters Safe or theirequivalent through the spaces between the opaque strips-of D when theline is clear or the semaphore-signal is at safety. In the drawings,Figs. 2 and 2 for the sake of illustration, showboth the danger-signaland the safety-signal in the visible positions.

The lever cl is so weighted that when it stands in theposition shown bydotted lines in Fig. 2 and by full lines inFig. 3 it is held 2 and intocontact with a spring (Z The clapper (1 carried by the armature d, atthe same time rings the bell (Z.

The circuits are as follows: The wire a is connected through thebinding-post 5 and wire '7 to the armature-lever (Z which is normally incontact with the insulated back-stop (1. This latter is connected to thecoils of the operating-electromagnet c", Figs. 2 and 11 to one terminalof the battery E. The

spring (Z is connected through the insulated post d and wire (Z to theother terminal of the battery E.

Both the described circuits are normally open; but when the movement ofthe lever a closes the circuit through a a at 01 a and through the coilsof the electromagnet d the bell rings and the visible signal (1 fallsfrom the position shown in Fig. 3 to the position shown by full lines inFig. 2. This fall of the signal (Z' causes the lever d to make contactwith the spring (Z and so closes the circuit from d, d", and (K throughC1 (Z armature d back-stop d coils (Z and wires 9, 10, and 11 to thebattery, producing a continuous ringing of the bell until the engineerpushes upward the button (i to lift the lever (i and its disk d up intothe position shown by dotted lines in Fig. :2, to be caught by theprojection on the armature-lever. The spring (1 then returns and breaksthe connection. Thisspring (Z performs several functions. It serves ascontact-maker for continuous alarm, a support for the indicator orsignal when shown, and a replacer of the said signal. Furthermore,supposing that at any time it is desired to test the battery and thesignal generally before starting on a journey, the engine-driver or aninspector can by pushing the spring (1 up to make contact with the lever(I complete the electric circuit, and if the bell rings properly theapparatus is in order. This danger-signal may be used with the singleform of levera, (shown on Figs. 2, 3, and 4 of the drawings accompanyingthe United States application, Serial No. 664,099, above mentioned;) butI prefer to use it with the double arrangement already referred to, sothat the bell d-mayserve also to give a signal (though not a continuousone) when the semaphore signal is at safety or line clear.

Referring now to the safety-signal part of the device, the circuit isfrom one terminal of the battery E, Fig. 2, through the wire 11,binding-post 60, and wire 12 to the coils of the operating-electromagnetd thence to the frame and armature (Z wire 13, binding-post 50, andconductor a to the contacts a Fig. 1, and wire a to the battery. One ofthe pole-pieces (Z of this magnet (1 is extended and cranked, as shown,so as to attract a second armature (Z as well as the armature 11', towhich the clapper d is fixed. This armature (l is fixed or fitted to adependinglever (1 held in place by two reversed springs (Z actinganddisposed in a similar manner to the springs c 0, above described. Thelever 61 carries the disk or, plate (1 on which the letters Safe or anyequivalent devices are marked in such a manner as (when the armature (Zis not attracted) to be concealed by the opaque parts of the spacedshutter D As soon,however,as the armature is attracted the bell d issounded and the letters or devices appear in sight until the secondlever a has ceased to vibrate sufliciently to complete the necessarycircuit.

The next part of my invention relates to the contact-bar for deflectingeither of the levers a a as desired, according to the positions of thesemaphore-signal. For this purpose I use a rocking lever, Figs. 5, 6,and 7, with two ends I) b similarly formed, but one, 1) heavier than theother, I), each end forming a contact-bar, as required. The lever b b ismounted on a shaft I)", carried by suitable brackets l), fixed in such aposition that the path of one lever a is above I) and that of the othera is above b The lever I) b is movedby a lever 13 on the shaft the leverb being connected by a wire, rod, chain, or cord N, Fig. 5, to the usualweighted lever of the semaphore-signal in such a manner that when thesemaphore is raised to danger the part b of the lever is raised, asshown, and when lowered to safety the part b is raised by the pulling ofb in the direction of the arrow, Fig. 5.

Figs. 5 and 6 show how the lever b b may be worked fromseveralsemaphore-signals by using a corresponding nu mber of levers-sayb b .b and forming in each lever a quadrant-shaped recess I), in which akey 00, fixed in the shaft 1), can work, and thus any one of the leversb b b -say b -ca n move the lever Z) b without interfering with ormoving the other levers-say Z1 (2 The part b of the lever being heavierthan I) will keep the engine-signal always at danger unless withdrawn tosafety. I further provide spring stops or buffers Z2 11 for each portionof the rocking bar 11 b so that thus the working part of the lattercannot get out of place by being pulled or dropped too far. Anotherfeature of this weighted rocking bar I) b is that it can be connected toa gate at a level crossing and warn the engineer whether the gateis openor closed.

I claim as my invention- 1. In a railway signaling apparatus, thecombination of two electric signals on an engine with two spring-leversalso on the engine or train, and connections between the levers andsignals, with a rocking contact-bar 011 the permanent way, having twocontact-arms, one adapted to deflect one of said levers when the line isclear and the other arin to deflect the other lever when the line isblocked, all substantially as described.
